Steam Coil Piping - Daikin Rebel Applied DPSA Installation And Start-Up Manual

Steam Coil Piping

Steam coils are provided without valves as a standard unit,
requiring field installation of valves and pipig. As an optionthe
steam coil coil is upplied with a two-way valve and actuator
motor from the factory. Refer to the submittal drawings to
determine unit configuration. The submittal drawing will also
have information about the line size connections.
The steam heat coil is pitched at 1/8ʺ (3 mm) per foot (305
mm) to provide positive condensate removal.
Refer to the certified drawings for the recommended piping
entrance locations. All piping penetrations must be sealed to
prevent air and water leakage.
NOTE: The valve actuator spring returns to a stem up
position upon power failure. This allows full flow
through the coil.
